Letters Patent No. 86,468, dated Febrrro/ry 2, 1869.

IMPROVEMENT IN' STAVE-DRESSING MACHINE.

The Schedule'refened to in these Letters Patent and making part of the n ame.

To all whom 'it fina/y concern Be it -known that we, PETER STEIGKEE and J AMES LEFEBER, of Cambridge City, in the county of Wayne, and State of Indiana, have invented anew and useful Improvement in Machines for Dressing Barrel-States; and We do hereby declare that the following is a full,

clear, and exact description thereof, which will enable t others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure l is a transverse section of our machine through x x of Figure 2, which latter is atop view of the machine.

Similar letters of reference indicate like parts.

This invention relates to improvements in machines for cutting beer-barrel staves, which are thinner at their centre than at their ends; and

It consists in the arrangement of the rotary cutter transversely of the rising and falling carriage, with its arbor or shaft parallel to the longitudinal movement of the latter, for the purpose of hollowing out a barrelstave longitudinally and transversely, with its centre thinner than its ends.

In the drawings- A A.A A, B B is the general frame ofthe machine.

Between the horizontal top-pieces B B, the lcarriage C is guided in its to-and-fro motion, under the cutterwheel D, the revolving plane of which is crosswise of the carriage, as shown. -The bearings of the shaft of the said wheel are afxed to the pieces B B.

the carriage, may be employed, or the curved parts d l may consist of cast-iron or other metal, in order to insure by its weight the proper contact of the carriage with the rolls b b.

When the wheels c e are used,'their tracks on, the carriage should be concave, or curved downward, to correspond to the curve of the parts d d, so that the vertical motion of the carriage will be possible.

The springs f j' are aiiXed to the top pieces B B, so that their free ends will bear upon the carriage, as shown in 2.

The wood being dressed, is shown in red color, being held by the fixed dog l and the adjustable dog m.

The rolls b b have bearings in the slotted plates/n, which'permit the adjustment of the rolls to and desired thickness of wood, a clamp-screw, a, serving to fasten each plate firmly to the frame.

We are aware of the patent grantedto Dixon Lewers,

December 24, 1867,'in which the cutter is arranged to operate transversely of an ordinary stave, and also oi' the patent granted to'VV. A. Ellis, July 3l, 1866, in which a table is arranged to move in curved guides for the purpose of hollowing outstaves, 'but we claim nothing shown in these patents, as they do not relate to our improvements.

Having thus described our invention,

We claim as new, and desire to secure by Letters Patentl The arrangement, herein described, ofthe transverse cutter D, and the rising and following carriage C, for A the purpose specified.
